You can use imadjust() in the Image Processing Toolbox. It's not interactive though. Or simply multiply your image by a factor between 0 and 1.

It can reduce it also. Read the help:
J = imadjust(I,[low_in; high_in],[low_out; high_out]) maps the values in I to new values in J such that values between low_in and high_in map to values between low_out and high_out.
Do you think the contrast would be reduced if low_out was 100 and high_out was 103, so that there was only a 3 gray level difference between the lowest gray level and the highest gray level? Sure it would.
